Specification forming vpart ot' Letters atent N o. 114,52". dated Uctober 11', 1864.

Be ity known that l, G. A. BALDwnv, of Boston, 'in the county of Sutt'olk andState of -ll1assachnsetts, have invented I a Chine-Blank .for Barrels; and I d o Vhereby declare that the following, takenl ,in'connection with the drawings which accompany and form part ot' thisspecification, is al description of my invention suflicient to enable thosefskilled in the art to This inventionhas for its object a provision for the easy and-ready repair of the ends of barrelstaves, or the part known as the chine y or chime of a barrel.

In all kinds of casks employed for packin g and transportation, the chines are liable to :become more or less injured or destroyed by 'ripping and'rolling then barrels. and such injury oftenA extending to the croze or groove in the staves which fastens'the heads of the barrel in position soon loosens the head'- pieces or makes .a Abreach into theV barrel. Suchfbreakages are moreor less imperfectlyrepaired, as circumstances and means-atA hand will allow.

My invention consists in a blank, or supplemental or auxiliary chine-piece, correspond-r ing in iateralcurvature to the curve ot' a cross'- sectionot' a stave and shaped at top to correspond with the end of a stave, and having otherwise a regular and even form ation, as I will proceed to describe, the entire shape'ct" ,the piece being 4determined bythe movement of the piece of wood from which the blank is to be cut in eonj unction with the movement of reducing-cutters of the machine employed for,

manufacturing the blanks.

Figurell of the drawings shows an linside view of the blank g.. Fig. 2, an edge view, Fig.

starve generally breaks in the croze, or for riav pair is cut down-to inthe-lower side ofthe croze-groove remains on the stave. lFrom vthis lip .the' blank is chamtered down tothe lower edge, leaving there a sufficient thickness of material to preventsplintering and tojallow the edge to abut properly against the 'outer surface o'fthe stave. x vTo use the blank the upper end of the broken stave istrimmed 'downto a sufficient v extent belowr the-breakage orto the groove or croze lin the stave, and so as to-leave a smooth outer surface thereon for the inner surface ot' the chine-blank to abut against, and then the blank is driven into the place previously Aoc- Vcupied by the'broken stave endor between the nextadjacent staves 'and'the'hoops and barrel-head the` lower ed ge of the chine bein g,

on the outer surface of the broken'staveand' the chine driven down so that the lip or projection on its inner surface shall abut against the barrelhead. The top ot the chine is then uniform in position with` respect to the'ends of the unbroken staves, and its outer surface only lprojects beyondthe o u'ter surface of the adjacent staves at its lower edge, which is se thin as not to project to an extent thatis practically injurious.

It is necessary-furthe blank to. have the formation shown-that is to say, with the lip or projection, anda plane surface (vertically) from this lip to the lower edge of the blank, insteadof constructing itq with a groove or croze like the croze in the inner surtace of a' barrel-stave, because such a groove (or the 4lip forming the b'ottomx side O t'it) would not admit` of -the blank being driven past the edge of the barrelfhead, whereas the thinness of thev blank below the'lp allows the blank to be driven Ybetweenthe edge of the barrelhead and the h'oop, until the lip comes against vthe head, when it ,is in position to h old the head and it is also necessaryto chamferk or taper theblankdown to the lower edge in order to permit the 'blank to set ush, or practically iiush, against the outer surface of the stave. I

With this invention barrelchimes maybe very easily and perfectly repaired,` requiring y no skill to 4out out the'piece and but very little skill to drive and fasten the blank Iin po- As a new article 0f manufacture, .the chinesition. They are to be; made, as are staves, blank, having aformntion snbstantallyas deof varying widths and-with curvatures corre; scribed.
